Customer Reviews (4.8 / 5 · 5 reviews)

Sofia ★★★★★

I popped these into a jig for a production run and the nylon patch held perfectly even with some vibration. The black oxide finish looks clean and the hex socket drive made them easy to install with a standard hex key.

Timothy ★★★★★

I was skeptical about the nylon patch holding, but these screws lock in place perfectly on my jig without any loosening during operation. The black oxide finish gives them a nice, durable look too.

Amelia R. ★★★★★

The hex socket drive really simplifies installation with a standard Allen wrench, and the black oxide finish feels durable. These bolts seated perfectly in my jig fixture with no stripping.
